Benefits of technology
This patent describes a book that can be used in an augmented reality system, an entertainment device that can be used in an augmented reality system, and an augmented reality system we offer for sale or use. The patent also describes a method for making a video image of a book that is more immersive and engaging using augmented reality. Overall, this technology can make it easier to use and enjoy books in a new and interesting way.
Problems solved by technology
However, the determination of the scale and orientation of elements of the scene, and hence of the virtual objects that are superposed on them, is a non-trivial task.

Embodiment Construction
[0033]A book, an entertainment device, an augmented reality system and a method for augmenting a video image of a book is disclosed. In the following description, a number of specific details are presented in order to provide a thorough understanding of the embodiments of the present invention. It will be apparent, however, to a person skilled in the art that these specific details need not be employed to practice the present invention. Conversely, specific details known to the person skilled in the art are omitted for the purposes of clarity where appropriate.
[0034]Referring now to FIGS. 2A and 2B, in an embodiment of the present invention a book 1000 has a plurality of rigid, turnable leaves (a so-called ‘board book’), and comprises fiduciary markers 1011, 1012 on each page 1001, 1002, as shown in FIG. 2A. A leaf will be understood to be a single turnable sheet or panel of a book and typically comprises a page on each side. FIGS. 2A and 2B show, by way of example, pages 1 and 2 (r...

A book for use in an augmented reality system comprises a plurality of leaves, each side forming a page of the book, with each page comprising a fiduciary marker. The book also includes a cover having larger dimensions than the book's leaves. Thus, the cover's extremhities extend beyond the outer edges of the pages. The inside of the cover comprises a first high contrast pattern along at least a first such extremity. An entertainment device for use in the augmented reality system comprises input means to receive a video image of the book, and image processing means to estimate a position and orientation of the book from a fiduciary marker of the book captured in the video image, to estimate a position and orientation of the first high contrast pattern, and to distinguish between one or more leaves of the book being turned independently of the cover of the book.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the benefit of and priority to GB Application No. 1208259.0, filed May 11, 2012, the entire disclosure of which is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an augmented reality system.[0004]2. Description of the Prior Art[0005]Augmented reality refers to the process of capturing a video image of an environment, and augmenting that video image with computer graphic elements (typically depicting virtual objects such as game characters that are to appear as if part of the environment). To provide a convincing augmentation, it is desirable for these computer graphic elements to be displayed in a manner consistent with the environment, particularly in terms of scale, range of motion, and viewing angle. Thus for example if the video image of the environment (referred to herein also as the ‘scene’) depicts a floor or table-top ...
